YONGYUTAI · Bipolar (BJT) · SOT-23
MMBT2222 from YONGYUTAI, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BASE | input | Base of the NPN transistor; VEBO max 6 V and V(BR)EBO min 6 V at IE=100µA. |
| 2 | EMITTER | passive | Emitter of the NPN transistor; emitter-base voltage limited to 6 V. |
| 3 | COLLECTOR | passive | Collector of the NPN transistor; VCBO 75 V, VCEO 40 V, continuous IC 0.6 A. |
